My NMD told me that flaxseed causes estradiol to decrease in preference of estriol. Estriol is supposedly good for PCa depending on how much ERb and ERa one has.
I have been on supraphysiologic testosterone (SPT) for a little over a year. I use an AI (letrozole) and my estradiol hovered around 20 pg/ml. Last month I added flaxseed to my diet (I think too much - I was consuming about an ounce or two a day). My estradiol dumped from the mid-20s to <4. I talked to my NMD and he thinks that if I monitored my estriol it would show a marked increase.
I've reduced my flaxseed intake to 1/10 oz a day and I've cut my AI dose in half. Next week I'm going to have my estradiol levels checked.
Thoughts? Good/bad/indifferent
